PCGH: exclusive benchmarks from AMDs Quad Crossfire

PCGH had the chance to do some hands-on sessions with a Quad Crossfire system in Munich with AMD. In the test system, two HD 3870 X2s worked together hand in hand. To measure the performance of four chips they used several programs like Crysis in DX10, UT3, Call of Duty 4 and 3DMark 06.
